SULKY-PLOW.

Patented Oct. 14,1913.

Original application filed November 16, 1911, Serial No. 660,564. Divided and this application filed March T0 ((ZZ whom it may concern Be it known that I, Lrwrs A. BUTTER- rnzLn, a cit zen of the United States of America, 1 ding at Ohicopee Falls, in the county of l-lampden and State of Massacnuscttr have invented new and useful Improvements in Sullrv-Plows, of which the following is a specification.

This invention relates to improvements in reversible sulky plows in which the line of draft is directly in line with the plow beam and the pole of the machine.

he present application is a divisional one of that filed November 16, 1911 under Serial Xo. 660,561.

The objects of the invention are: To provide means for adjusting the mold-boards transversely of the machine so as to make the machine cut a wider or narrower fur row, as desired. To provide means for retaining the pole and plow-beam always in direct line with each other in order to obviate the side draft and at the same time make the machine draw easier when in use. To provide a quick entrance of the moldboards into the soil.

Further objects and the nature of the in vention will be fully set forth in the specification and particularly pointed out in the claims. In the drawings forming part of this application, Figure 1 is a plan View showing the general arrangement of the machine, illustrating the beam which supports the mold-boards in direct alinement with the draft-pole, and illustrating the hand-lever for reversing the mold-boards; also showing the dog-shaft for lifting the mold-boards from the furrow when the end is reached and before starting back on the return trip. Fig. 2 is a vertical, sectional view on the line 2-2 of Fig. 1 showing the lever construction in side elevation for operating the dog-shaft, the trip device for the dog-shaft, and the lever for varying the depth of the furrow. Fig. 3 is a side elevation of Fig. 1 clearly illustrating the landing lever construction for varying the width of the furrow, one end of the dog-shaft, and the teeth with which the dog engages for elevating the mold-boards, and the hand lever for reversing the mold boards. Fig. 4: is an elevation showing one of the moldboards in the furrow, and the other in an elevated position, the end of the beam on Serial No. 684,150.

which the mold-boards are hung, and the hand-lever for swinging the mold-boards from an operative to an inoperative position. Fig. 5 is a detailed View of the footlever for tripping or releasing the dogshaft and allowing the mold-boards to drop, and the hand-lever for varying the depth of the cut.

Referring to the drawings in detail, a designates the main frame to which the axle stubs are attached for supporting the wheels I). This frame has a rearward extension portion, indicated at c, and is strengthened by means of the cross-bar (Z.

w designates a U-shaped frame-bar the rearwardly extending portion of which is loosely attached to one of the integral arms f of the main frame a at 10 (See Figs. 1 and 2). The outer end of the frame-bar w is attached to the casting 0 and is then bent at right angles parallel with the axle of the wheels I) The beam of the plow is indicated at 7 and it will be observed that it is in direct line with the draft pole 8 of the machine. This beam is rigidly secured to the part c of the frame a by means of a clamp 9 which is rigidly attached to the beam by means of the bolts 10. The rear surface of the clamp 9 is provided with teeth or indentations 11 for the purpose of rigidly securing the blocks 9 to the clamp 9 at 90 apart. The bolt 9 secures these blocks to the clamp 9, see Fig. 2.

The hand lever 12 for reversing the moldboards has a sliding rod 13 carrying a looking bolt 13 at its lower end. This rod is adapted to be actuated by the operator by moving the lever 14 against the tension of the spring 15. The locking bolt 13 drops into the openings 13 in the block 9 The hand-lever 12 is secured at its lower end to the block 16 which turns freely on the beam 7 when the bolt 13 is withdrawn. Secured to this block are the two mold-boards 17 and 18 by means of the arms 17 and 18 at right angles to each other so that when the lever 12 is unlatched from the block 9 one moldboard may be elevated and the other de-- It should be particularly observed that the arms 17 and 18 are so attached to the block 16 that when one mold-board is in use the line of draft coincides with the axis of the beam 7 and the pole 8, thereby overcoming any side-draft, which is a very important feature resulting in ease of operation of the machine. When in use, one arm stands in a vertical plane and the other in a horizontal one, as shown in end view Fig. 4. The extent of movement therefore of the handlever is ninety degrees (90). The forward portion 21 of the bar to is loosely connected to the arms f of the main and axle frame a at the point 10 see Fig. 2. The rearwardly extending part 23 of this bar is rigidly secured to the cross-bar 2 L at the part 25 and terminates beyond the clip 26. The parts to, 21, and 23 form therefore a continuous U- shaped bar.

27 designates a lever for throwing the mold-boards into and out of the land so as to vary or gage the width of the furrow being turned. This lever is pivoted to the part 23 of the U-shapedbar at the point 28 and is provided with a locking belt which engages the rack 29 which is also secured to the part 23; The lower end of this lever is connected to a link 30 at the point 31, the inner end of the link being attached to a forward extending bar 32 at 32 which is part of the mainframe a. The clips 26 and 26 are made integral with the frame a and af ford a bearing and support for the part 23.

It will be seen from this construction that when the lever 27 is moved forward and backward, the U-shaped bar 21 will be moved into the dotted line position indicated. at 21 thus causing the mold-boards to cut a wider or narrower furrow, as desired. This construction of the bars to, 21, 23, and 32, is in effect, a two-part frame, one movable relative to the other by means of the lever 27 which is known as the landing lever and turns about the point 7.0 as a center, causing one of the supporting wheels Z) to be moved forward and the other rearward, as shown at If, in Fig. 1. The frame a and the axle members will of course assume a position corresponding with the dotted line positions indicated in Fig. 1. It will therefore be seen that when the landing lever 27 is operated, the pole 8 and beam 7 will always remain in line with each other and with the land side of the plow in use, and that one of the supporting wheels 5 will be shifted forward and the other rearward, or vice versa, depending upon the width of the furrow to be turned,the two part frame permitting this result to be accomplished.

What I claim. is

1. In a reversible sulky plow, in combination with the main frame thereof, and sup- 1 and means to move one part of the said frame to vary the Width of cut of the furrow, whereby the pole is retained in a fixed position and one wheel is moved forward, and the other rearward.

4. In a reversible sulky plow, the combination with a single beam, two mold-boards supported thereon, the pole and beam being always in line with each other, a two-part frame, and means to shift one frame relative to each to move one supporting wheel forward and the other rearward, whereby the width of the furrow to be cut may be varied.

5; In a reversible sulkyplow, the combination with the two supporting wheels, a single beam member on which right and lefthand mold-boards are pivotally supported, a main frame, a two-part frame, one side of which is slidably connected to the main frame and pivotally connected to the main frame at its opposite side, a landing lever to move the slidably connected part of the twopart frame, whereby the supporting wheels are shifted in alternate directions to vary the width of the furrow being cut.

6. In a reversible sulky plow, a main frame, supporting wheels therefor, a single beam, a pole, right and left-hand moldboards pivotally mounted on the beam; the beam, pole, and land side of the mold board in use being always in line, a two part frame connected to the main frame, and means connected to the two-part frame to shift one supporting wheel forward and theother rearward, whereby the width of the furrow may be varied, substantially as described.

7. A reversible sulky plow having a single beam on which are pivotally mounted two mold-boards, a pole in line with said beam, a two-part frame, means for moving one part of the two-part frame relative to the other part, the land side of the mold-board, when in use, and the beam and pole being in line with each other, whereby all side draft is prevented.
